The Xilinx USB cable driver is a software component that enables communication between a Xilinx USB programming cable and a Windows computer. These cables are commonly used with Xilinx development boards and programmable logic devices (PLDs) such as FPGAs (Field-Programmable Gate Arrays) for programming, debugging, and testing purposes.

The Xilinx USB cable driver allows Windows operating systems to recognize and interact with Xilinx hardware programming tools, such as the Xilinx Platform Cable USB, USB-JTAG cable, or similar devices. It is typically required when working with Xilinx tools like Vivado, ISE, or ChipScope for programming FPGAs and other programmable devices.
